Abstract

The invention relates to a connection or distribution piece for heatable hoses. The hose heating is carried out by means of heating conductors which are arranged running longitudinally in or on the hose wall. The connection piece consists of a connection element, inserted into the hose internal diameter, and insulation. According to the invention, the insulation is a sleeve tube (1), divided in the longitudinal axis, whose two half shells (11, 12) can be fixed on one another via connection means (111, 112, 121, 122), with the free ends (21) of the hoses (2) to be connected covered. On the outer surface of the connection element (3), there are integrally formed material steps (31, 32), increasing in thickness in the insertion direction, distributed on the circumference in the region of the insertion into the hose internal diameter (22). These material steps (31, 32) enter into a clamping effective connection with compression webs (113, 114, 123, 124) which are integrally formed on the inner circumference of the half shells (11, 12) when the hose (2) is retained on the connection element (3). <IMAGE>

Keksinnon kohteena on låmpoeristetty liitos- tai jakokappale kuumennettavia letkuja vårten, joissa letkun låmmittåminen tapahtuu såhko-10 kuumennusjohtimien vålityksellå, jotka on jårjestetty pitkittåin etenevåsti letkun seinåmåån tai seinåmålle, joka kappale muodostuu letkun keskionteloon asetetusta liitoselementistå ja eristyksestå.The invention relates to a thermally insulated connection or manifold for heated hoses, in which the heating of the hose takes place via electric heating conductors arranged in a longitudinally progressive manner in the wall of the hose or in a wall element formed by the middle of the hose.

Hyodyllisyysmallista DE-GM 86 22 603.7 tunnetaan kuumennettava letku, 15 jossa såhkokuumennusjohdin on jårjestetty rinnan keskiontelon kanssa letkun seinåraåån. Keskiontelo on siirretty letkun akselista yksisivui-sesti siten, ettå toisella sivulla on poikkileikkauksen paksunnos, johon såhkokuumennusjohdin on upotettu. Keskiontelon ja såhkokuumen-nusjohtimen vålinen letkuseinåmåalue on poikkileikkaukseltaan tålloin 20 ohuempi kuin såhkokuumennusjohtimen ja letkun viereisen pinnan vålinen letkuseinåmåalue.A utility hose is known from the utility model DE-GM 86 22 603.7, in which an electric heating line is arranged in parallel with the central cavity in the wall wall of the hose. The central cavity is displaced from the shaft of the hose on one side so that the other side has a cross-sectional thickening in which the electric heating conductor is embedded. The hose wall area between the central cavity and the electric heating conductor is then 20 thinner in cross section than the hose wall area between the electric heating conductor and the surface adjacent to the hose.

Hyodyllisyysmallista DE-GM 87 04 903.1 tunnetaan låmpoeristetty liitos- tai jakokappale kuumennettavia letkuja vårten, joka muodostuu 25 letkun keskionteloon osittain asetetusta, låmmonjohtokykyisestå mate-riaalista valmistetusta liitoselementistå ja eristyksestå. Kuumennet-tavien letkujen såhkokuumennusjohtimet on saatu vapaisiin påihin poistamalla letkun seinåmå, ja ne on asetettu letkujen keskiontelosta ulostyontyvien liitoselementtien osa-alueiden ympårille. Såhkokuumen-30 nusjohtimen liitin on johdettu ulos tåltå alueelta, ja yhdistettåvien letkujohtojen vapaiden påiden ja liitoselementin letkujohdoista ulostyontyvien osa-alueiden sekå liitoselementin nåiden ulostyontyvien osa-alueiden ympårille kååmittyjen såhkokuumennusjohtimien vålinen yhdistelmå on puristettu irrottamattomaksi kokonaisuudeksi eritysma-35 teriaalista koostuvalla vaipalla. Vaikka tållå tavalla saadaan aikaan kuumennettavien letkujen moitteeton liitos liitoselementin kuumenta-misen vålityksellå, tållaisen liitoksen valmistaminen on kallista ja 2 90299 1 tyolåstå, koska letkujen liitoskohta sekå såhkoliitos on asetettava ruiskupuristimeen ja puristettava siinå eristysmateriaalilla.A utility model DE-GM 87 04 903.1 discloses a thermally insulated connection or manifold for heated hoses, which consists of a connection element and insulation made of a thermally conductive material partially placed in the central cavity of the hose. The electric heating conductors of the hoses to be heated are obtained at the free ends by removing them from the wall of the hose and are placed around the parts of the connecting elements projecting from the central cavity of the hoses. The connector of the electric heating conductor 30 is led out of this area, and the free ends of the hose lines to be connected and the parts protruding from the hose lines of the connecting element and the connection element Although in this way a perfect connection of the heated hoses is achieved by heating the connecting element, the manufacture of such a connection is expensive and laborious, since the connection point of the hoses and the electrical connection must be placed in an injection molding machine and pressed with insulating material.

Tåmån keksinnon tavoltteena on tåmån vuoksi saada aikaan parannettu 5 liitos- tai jakokappale kuumennettavia letkuja vårten, joka saa yksinkertaisella tavalla aikaan liitospaikan tiheån ja eriståvån kerroksen letkunkappaleiden våliin. Parannuksen mukaan kerros on pituusakselille jaettu suojaputki, jonka molemmat puolikuoret ovat asetettavissa liitoselimien vålityksellå påållekkåin yhdistettåvien 1Q letkujen vapaita påita suojattaessa, ja liitoselementin ulkoiselle pinnnllo letkun keskiontelon sisååntuloalueelle on muodostottu kehalli· jaet tuja, s i .sa;int ydnt o.suunnassa paksuudeltaan 1 i sååntyviå materiaa1 i porrastuksia, jot.ka tulevat puolikuorten sisåkehålle muodostettujen paineolakkeiden kanssa vaikutusyhteyteen letkua liitoselementtiin 15 asennettaessa.It is therefore an object of the present invention to provide an improved connection or manifold for heated hoses, which in a simple manner provides a connection point between the hose pieces of the dense and insulating layer. According to the improvement, the layer is a protective tube divided on the longitudinal axis, both half-shells of which can be placed via the connecting members to protect the free ends of the 1Q hoses to be superimposed, and a circumference is formed on the outer surface material1 i steps which come into contact with the pressure shoulders formed on the inner circumference of the hemispheres when the hose is installed in the connecting element 15.

Tålloin on osoittautunut edulliseksi, etta puolikuorien, yhdistettåvien letkunpåiden, 1 i i toselementtien letkujen keskionteloista ylos- tyontyvien osien ja puolikuorten våliseen sisåtilaan johdettujen 20 såhkokuumenneusjohtimien våliin jååvå sisåtilå voidaan tåyttåå eris-tysmassalla.In this case, it has proved advantageous that the interior space between the half-shells, the hose ends to be connected, the parts protruding from the central cavities of the hoses of the elements and the electric heating conductors 20 between the central cavities of the hoses can be filled in the interior.

Kahden letkun yhdiståminen keksinnon mukaista liitos- tai jakokappa-letta kåyttåmållå on yksinkertaista. Liitoselementti asetetaan ensin 25 kahden yhdistettåvån letkun keskionteloihin niiden vapaisiin påihin.It is simple to connect two hoses using a connection or manifold according to the invention. The connecting element is first placed 25 in the central cavities of the two hoses to be connected at their free ends.

Nåmå letkunpååt on valmistettu siten, ettå såhkokuumennusjohtimet on upotettu vapaisiin letkunpåihin poistamalla letkuseinåmå ja yhdistetty toistensa kanssa såhkoå johtavasti. Kun tåmå såhkoå johtava liitos, joka on yleenså juotos, on tehty, tåmå letkuliitos asetetaan jaetun 30 suojaputken puolikuoren påålle. Tåmån jålkeen ylempi puolikuori vedetåån alemman puolikuorelle, jolloin koko liitos- tai jakokappale peittyy. Eriståva sisåmassa voidaan syottåå molempin puolikuorien låpi jåljellejååvåån sisåtilaan ennen tåtå påållevetåmistå tai sen jålkeen. Eristys voi muodostua vaahtoavasta materiaalista, joka 35 vaahdottan liitos- tai jakokappaleen jåljellejååvåt sisåtilat ja muodostaa nåin tiiviin eristysvaipan.These hose ends are made in such a way that the electric heating conductors are embedded in the free hose ends by removing them from the hose wall and connected to each other in an electrically conductive manner. Once this electrically conductive connection, which is usually soldering, has been made, this hose connection is placed over the half shell of the split 30 conduit. The upper half shell is then pulled onto the lower half shell, covering the entire connection or manifold. The insulating core can be fed through both half-shells into the remaining interior before or after being overlaid. The insulation may consist of a foamable material which foams the remaining interiors of the connection or manifold and thus forms a tight insulating jacket.

Kuviossa 1 esitetåån pitkittåisleikkaus liitoskappaleesta kahden 20 letkun 2 pitkittåisliitosta vårten. Kuviossa nåkyy ainoastaan kahdesta puolikuoresta 11,12 muodostuvan suojaputken 1 alempi puolikuori 12. Tåhån puolikuoreen on asetettu letkujen 2 vapaat pååt, jotka oli aikaisemmin yhdistetty toisiinsa liitoselementillå 3. Tåmå liitos tapahtuu siten, ettå liitoselementin 3 osa-alueet asetetaan letkujen 25 2 keskionteloon niiden vapaisiin påihin. Liitoselementin 3 keski- onteloon asetetuilla osa-alueilla on kehålle tyontosuuntaan jaettuja, paksuudeltaan suurenevia materiaalikerrostumia 31,32, joiden ansiosta letkujen påitå ei voida vetåå helposti irti liitoselementistå 3. Puolikuoreen 12 on muodostettu vapaiden påiden alueelle painekanavia 30 123,124, jotka tulevat puristavaan vaikutusyhteyteen materiaalipor- rastuksien kanssa letkuliitosta puolikuoreen asetettaessa. Tålloin joustava letkunosa, joka sijaitsee liitoselementin 3 sisååntyonnet-tyjen alueiden ylåpuolella, painuu lisåksi materiaaliporrastusten 31,32 taaksc. paineolakkeiden 123,124 vaikutuksesta.Figure 1 shows a longitudinal section of the connecting piece along the longitudinal connection of the two hoses 2. The figure shows only the lower half-shell 12 of a protective tube 1 consisting of two half-shells 11,12. In this half-shell are placed the free ends of hoses 2, which were previously connected to each other by a connecting element 3. This connection is made by inserting parts of the connecting element 3 påihin. The sub-areas placed in the central cavity of the connecting element 3 have circumferentially increasing layers of material 31,32 in the working direction, due to which the end of the hoses cannot be easily pulled out of the connecting element 3. The half-shell 12 is formed with pressure channels 30 123,124 in the free end region. with hoses when inserting the hose joint into the half shell. In this case, the flexible hose part, which is located above the inlet areas of the connecting element 3, is further depressed behind the material steps 31, 32. by the effect of pressure shoulder 123,124.

Tållå tavoin liitoselementien 3 sisååntyonnetylle alueelle saadaan aikaan låhes irtoamaton letkunpåån lukitus. Puolikuorten 11,12 vapaat 35 4 90299 1 pååt on muodostettu lisåvarmistusta vårten rengaspuristimiksi 125, 126. Kun molempien letkunpåiden ja liitoselementin 3 vålinen yhdis-telmåliitos asetetaan puolikuoreen 12 rengaspuristimien 125,126 alueelle, saadaan aikaan lukitus, joka saa puolestaan aikaan rengas -g maisen lukituksen puolikuoren sisåtilaan puolikuorta 11 (ei esite tty piirustuksessa) puolikuorelle 12 asetettaessa. Tåhån sisåtilaan voidaan ennen molempien puolikuorten 11,12 yhdiståmistå sijoittaa juokseva eristysaine, joka tåyttåå puolikuorten yhdiståmisen jålkeen tåysin puolikuorten ja yhdistelmåletkuliitoksen våliin jååvån siså-1Q tilan.

Eristysaine voidaan syottåå puolikuorten 11,12 yhdiståmisen johdosta muodostuneeseen sisåtilaan inyos jålkeenpåin vastaavan tåyttoaukon kautta. Tålloin kysymykseen voi tulla vaahtoava eristysaine, joka tåyttåå syoton 15 jålkeen tiiviisti ja eriståvåsti myos tåyttoaukon.In this way, an almost inseparable locking of the hose end is provided in the inserted area of the connecting elements 3. The free ends 354 90299 1 of the half shells 11,12 are formed as ring clamps 125, 126 for additional securing arms. into the interior when placing the half shell 11 (not shown in the drawing) on the half shell 12. Prior to joining the two half-shells 11,12, a flowable insulating material can be placed in this interior, which completely fills the inner-1Q space between the half-shells and the composite hose connection after joining the half-shells. The outflow of insulating material is prevented by ring presses 125,126 in the free ends of the half-shells 11,12. The insulating material can be introduced into the interior formed as a result of the joining of the half-shells 11,12 inyos afterwards via a corresponding filling opening. In this case, a foaming insulating material may come into question, which also fills the filling opening tightly and insulatingly after feeding.

Ennen puolikuorten 11,12 yhteenliittåmistå on suoritettava vielå kuumennuslankojen 23,24 såhkoinen yhdiståminen, joka on yleenså juotos 231.Prior to the joining of the half-shells 11,12, an electrical connection of the heating wires 23,24, which is usually soldering 231, must still be carried out.
